A process for the preparation of Imipenem (formula (I)) or its hydrates comprising (i) deprotection of a carboxylic ester via catalytic hydrogenation in the presence of a catalyst deactivating agent and/or (ii) rapid dissolution of Imipenem in water at high temperature, followed by rapid cooling and isolation of the Imipenem in order to improve yield and purity and facilitate preparation of sterile Imipenem.
一种制备Imipenem(式(I))或其水合物的方法,包括(i)在催化剂去活化剂的存在下通过催化氢化去除羧酸酯的保护基,和/或(ii)在高温下快速将Imipenem溶解于水中,随后快速冷却并分离Imipenem以提高产率和纯度,并便于制备无菌Imipenem。
